Application April 21, 1955, Serial No. 502,964

10 Claims. (Cl. 155-106) This invention relates to articles of furnitureand more particularly to articles of repose for supporting the body of aperson, wherein a back-reset, seat and leg-rest are movable in apredetermined relationship relative to a support.

An object of the invention is to provide an article of repose of abovedescribed type with an advantageous mechanism for controlling themovements of the legrest in dependence on movements of the back-rest.

Another object of the invention is to improve on the construction ofarticles of repose as now ordinarily made.

Other objects and structural details of the invention will be apparentfrom the following description when read in conjunction with theaccompanying drawings forming part of this specification, wherein:

Fig. 1 is a side elevational view of a reclining armchair according tothe invention, a portion of a side wall being broken away,

Fig. 2 is a side elevational view of the reclining armchair of Fig. 1,wherein however the movable members of the chair are in a reclinedposition, 1

Fig. 3 is a side elevational view of another embodiment of an armchairaccording to the invention, a portion of a side wall being broken away,

Fig. 4 is a side elevational view of the armchair of Fig. 3, whereinhowever the movable members of the chair are in the reclined position,

Fig. 5 is a side elevationalview of a further embodiment of an armchairaccording to the invention, a portion of a side wall being broken away,

Fig. 6 is a side elevational view of the armchair of Fig. 5, whereinhowever the movable members of the chair are in the reclined position,

Fig. 7 is a side elevational view of still another embodiment of anarmchair according to the invention, a portion of a side wall beingbroken away, and

Fig. 8 is a side elevational view of the armchair of Fig. 7, whereinhowever the movable members of the chair are in the reclined position.

Referring now to Figs. 1 and 2, 10 generally indicates a support havingside walls 12 and 14 connected with each other in any suitable way.

A back-rest 16 and a seat 18 are swingably mounted on said support 10 at20. The upper end of a first link or guiding link 22 is swingablymounted on a transverse rod 24 mounted on the support 10. The upper endof a second link or guiding link 26 is swingably mounted on a transverserod 28 carried by the support 10. A bent bar 30 is pivoted to the lowerends of said links 22 and 26 at 32 and 34 respectively. The upper end ofsaid bent bar 30 is rigidly connected with a board 36 extending acrossthe chair. Said bent bar 30 and the board 36 rigid therewith form athird link or controlling link generally indicated by 38 of a linkage tobe described hereinafter. The bent bar 30, the first link 22 StatesPatent 0 2,788,058 Fatented Apr. 9, 1957 and the second link 26 arearranged substantially in the center of the chair.

The upper end of another link or arm 40 (in some of the claims referredto as fifth link) is pivotally connected with the seat 18 at 42. Saidlink 40 having a slot 44 slidably engaged with a pivot 46 arranged onthe link 38. The lower end of the link 40 is pivoted at 48 to one end ofa link or bar 50 (in some of the claims referred to as fourth link), theother end of which is pivoted to an intermediate point of a leg-rest 52at 54. The upper end of the leg-rest 52 is pivoted at 56 to the crossboard 36 of the link 38.

The movements of the linkage 22, 26, 38, 40, 50, 52 described above arecontrolled in dependence on the movements of the back-rest 16 by meansof a connecting link 58 pivoted to a lower extension of the back-rest 16at 60 and to an intermediate point of the link 26 at 62.

On each side of the chair another connecting link 64 (only one beingshown) is pivoted to a lug 66 of the cross board 36 at 68 and to theseat 18 at 70. The pivot 70 is well above the lower surface of the seat18.

The connecting link 64 controls the movements of the seat 18 independence on the movements of the linkage 22, 26, 38, 40, 50, 52 andthus through the connecting link 58 in dependence on the movements ofthe back-rest 16. Y

Fig. 1 illustrates the movable members of the chair in the sittingposition. Upon a rocking of the back-rest 16 about its pivot 20 themovable members of the chair are brought into the position shown in Fig.2 by means of the linkage described above. In said reclined position ofFig. 2 the cross board 36 being propelled forwardly covers the spacebetween the front end of the seat and the rear end of the leg-restcreated by the forward propelling of the leg-rest.

Fig. 3 illustrates the sitting position of the movablemembers of thechair while Fig. 4 i1lustrates the extreme reclined position thereof.

According to the embodiment of a reclining armchair shown in Figs. 5 and6, again the mechanism of the chair is substantially the same as that ofthe chair shown in Figs. 1 and 2. However according to Figs. 5 and 6 thesecond link 226 has a rearward extension 274 rigid therewith and theconnecting link 258 being pivoted to the back-rest 216 at 260 is pivotedto said extension 274 of the link 226 at 276.

Fig. 5 illustrates the sitting position of the movable members of thechair and Fig. 6 illustrates the movable members of the chair in theextreme reclined position.

The embodiment of an armchair shown in Figs. 7 and 8 is with respect toits mechanism substantially similar to that shown in Figs. 1 and 2.However according to Figs. 7 and 8 the connecting link 364' is pivotedto the seat 318 at 370 at a point near to the lower surface of the seat318. The other end of said connecting link 364 is pivoted at 378 to abracket 380 arranged on the bar 330 forming a portion of the link 338.

The low arrangement of the pivot 370 eliminates damage to the upholsteryby the connecting link 364 during relative movements by the said linkand the seat.

Fig. 7 illustrates the movable members of the chair in the sittingposition while Fig. 8 illustrates said members in the extreme reclinedposition.

Preferred embodiments of the invention have been described, but it isunderstood that this disclosure is for the purpose of illustration andthat various changes in shape and proportion of parts, as well as thesubstitution of equivalent elements for those herein shown and described may be made without departing from the spirit and scope of theinvention as set forth in the appended claims.

Suitable stops for limiting the sitting and extreme reclined positionsmay be provided on the chair and/or locking means may be arranged forholding the movable members of the chair in any desired position.
